Try each one before opening the answer. Each comes with a short explanation.
- Q1 · NUST NET Past Paper 07 · Sequences and Series
The 20th term of the arithmetic progression 7, 11, 15, ... is:
- A.83
- B.87
- C.79
- D.80
Show answer
Answer: A. 83 — a₂₀ = 7 + 19 × 4 = 83.
- Q2 · NUST NET Past Paper 08 · Sequences and Series
If 4, x, 9 are in geometric progression, then x equals:
- A.6.5
- B.±6
- C.36
- D.5
Show answer
Answer: B. ±6 — x² = 4 × 9 = 36 ⇒ x = ±6.
- Q3 · NUST NET Past Paper 05 · Sequences and Series
Which term of the arithmetic progression 3, 8, 13, ... is 98?
- A.19th
- B.20th
- C.21st
- D.18th
Show answer
Answer: B. 20th — 3 + 5(n − 1) = 98 ⇒ n − 1 = 19 ⇒ n = 20.
